连字符 - 负号 -

The Hyphen-Minus symbol is not a punctuation character. It is typically used both as a hyphen to connect words and as a minus sign in mathematical expressions or numerical ranges.

The word 「hyphen」 is derived from the Latin word 「hyphen,」 which in turn comes from the Greek word 「huphen,」 meaning 「together」.

Unicode has several hyphen characters. The hyphen symbol ‐ differs in terms of width (it is bolder). The Hyphen Bullet ⁃ looks even bigger, and it's primarily used as a bullet point or list marker.

符号 「连字符 — 负号」 包含在 「基本拉丁字母」 块的 「ASCII标点符号」 子块中，并在1993年作为Unicode版本1.1的一部分获得批准。
